Abstract: A power amplifier for a plate load (11) of an AM, RF transmitter includes plural switching stages each powered by a DC source. Each stage is switched from non-sourced to saturation in response to the amplitude of a source (18) exceeding a threshold amplitude for the stage; each stage has a different threshold. The thresholds and source are arranged so that responses derived between output terminals of the stages change between zero and predetermined amplitudes as the source amplitude changes relative to the thresholds of the different stages. The responses of the different stages are summed. A triangular wave (71) having a small constant maximum amplitude relative to the source maximum value effectively changes the threshold of each stage. From time to time the thresholds of different stages are changed so that at different times different stages are in non-sourced and conducting for the same amplitude of the modulating source, while providing the same summed response for the same amplitude of the modulating source.

Abstract: In a parallel pipelined instruction processing system, one of a plurality of instruction processing units receives an input operand designated by a corresponding instruction of a given instruction block, through a corresponding input operand fetch unit from a data register block. A next address generation unit generates an address for an instruction block succeeding to the instruction block being executed. A branch address generation unit generates an address for a branch destination instruction block. When there is executed an instruction which is included in an instruction block after one machine cycle and which requires the next address supplied from the next address generation unit as an input operand the one instruction processing unit receives the next address directly from a short path control unit. In this case, the reading of the instruction block and the generation of the next address are concurrently executed, and the reading of the input operand and the generation of the branch address are concurrently executed.

Abstract: A semiconductor device comprises a semiconductor substrate 1 formed with a diffusion layer; a first level gold-metallization layer 2 formed on the semiconductor substrate; a first inter-layer insulating film 3 formed on the first level metallization layer 1; a second level Au-metallization layer 4 formed on the first insulating film 3; a second inter-layer insulating film 5 formed on the second level metallization layer; and a third level gold-metallization layer formed on the second insulating film 5. As the diameter or short side of the through hole 3a is smaller than twice the film thickness of the second gold-metallization 4, gold grows isotropically from the wall surface of the through-hole, and at the time when deposition thickness reaches half the short side of the through-hole, the through-hole can be completely filled with gold and the gold-deposition surface becomes even. 
     According to the present invention, steps caused by a through-hole formed in an inter-layer film can be completely filled with metallizing material. This makes it possible to form another through-hole just over the through-hole, or separated metallization contacts just over the through-hole. Therefore, device element can be highly integrated thus markedly improving quality and production yield.

Abstract: The invention relates to a calibration cycle for an ANC (active noise control) system having at least one loudspeaker (1) and at least one microphone (2). In this arrangement, the calibration signal radiated by the loudspeakers is mixed with other signals such as, for example, music, and wholly or partially masked by these so that it is not felt to be so disturbing by the vehicle passengers. The additional masking signal (which is present as electrical variable) is mathematically eliminated in the calculation of the complex transfer function (the purpose of the calibration cycle). The transfer functions required for operating the ANC system can thus be updated more frequently without annoying the passengers, as a result of which the ANC system can be operated more effectively. <IMAGE>

Abstract: A method and means for encoding data written onto an array of M synchronous DASDs and for rebuilding onto spare DASD array capacity when up to two DASDs fail. Data is mapped into the DASD array using an (M-1)*M data array as the storage model, where M is a prime number. Pairs of simple parities are recursively encoded over data in respective diagonal major and intersecting row major order array directions, the encoding traverse covering a topologically cylindrical path. Rebuilding data upon unavailability of no more than two DASDs merely requires accessing the data array and repeating the encoding step where the diagonals are oppositely sloped and writing the rebuilt array back onto M DASDs inclusive of the spare capacity.

Abstract: 2.1 For power-saving purposes, it is normal in cordless telephones for the transmitter-locating device which is contained in the mobile station to be operated only during specific transmitter locating periods, interrupted by fixed pauses. 2.2 In order to avoid the associated disadvantage of the rigid response time to a call arriving in the fixed station, a setting device (EV) for manual setting of the pause period (TP) is provided in a first embodiment of the mobile station (MS) according to the invention. In a second embodiment of a mobile station (MS'), the pause period (TP) is modified in the mobile station (MS') according to the charging state of the battery (AK) which is contained in the mobile station, in such a way that the pause period (TP) becomes longer when the battery charge decreases and becomes shorter when the battery charge increases. A detection and control device (DS) which has either a voltage detector (SPD) or a current detector (STD) serves to determine the respective charging state. 3.

Abstract: When there are unused communication channels, it is checked whether an attribute of an image associated with transmission image data indicates color image data or monochrome image data. If the transmission image data is monochrome image data, the image data is transmitted through one of B channels of a line. If the transmission image data is color image data, and two B channels can be used, bulk transmission is performed by simultaneously using the two B channels. If it is determined that the two B channels cannot be simultaneously used, the image data is transmitted by using one of the B channels which is in a unused state.

Abstract: Improvements are made to standard run length encoding compression techniques to permit frequently occurring repeated bytes to be dynamically redefined or reset to a default value such as a blank character, repeated multiple byte units or strings to be more efficiently coded and run length encoded enhancements allow compression of data where characters are represented by multiple bytes. The Sequence Control Byte (SCB) is modified to communicate indications to a receiver that the compression mode of 1 to N bytes per character is being changed and to indicate what the change is or that a common master repeat character frequently encountered in data is being redefined to be another character or that characters are going to be encoded in multiple bytes. The SCB format which is well known in the prior art is modified to include specific bit patterns or codes in the first two bits of the SCB byte to indicate setting of the bytes per character encoding mode to a different value, resetting the encoding mode to a default value or redefining a commonly repeated character or defining a character to be multiple bytes or a string of characters which may be multiple byte characters. The other six bits of the SCB are assigned code values unused in the prior art to indicate the number of times that a defined character is to be repeated, whether a master character that has been defined is to be repeated or whether a character string is to be repeated. Two fields of data are thus formatted in the SCB with new values to indicate to a receiver these new criteria.

Abstract: A neuron (100) has a null-inhibiting function so that null inputs do not affect the output of the neuron (100) or updating of its weights. The neuron (100) provides a net value based on a sum of products of each of several inputs, and corresponding weight and null values, and provides an output in response to the net value. A neural network (40) which uses such a neuron (100) has a first segmented layer (41) in which each segment (50-52) corresponds to a manufacturing process step (60-62). Each segment of the first layer (41) receives as inputs measured values associated with the process step (60-62). A second layer (42) connected to the first layer (41) is non-segmented to model the entire manufacturing process (80). The first (42) and second (43) layers are both unsupervised and competitive. A third layer (43) connected to the second layer (42) then estimates parameters of the manufacturing process (80) and is unsupervised and noncompetitive.
